Thanks for your reply.The version of jbpm is 7.5.0.Final, tomcat 8.5.15, and the configuration information of kie-wb is shown below:
There are 3 BPM projects deployed through kie-wb, 1 drools, and 20 BPM projects deployed directly on kie-server through the rest interface.

At present, we try to deploy kie-wb services separately on cloud servers, and the memory footprint will exceed 1G without adding any containers.
We want to deploy a kie-wb service, multiple kie-server services, kie-wb without any containers, all via the rest interface of kie-server, and the memory footprint of kie-wb can be controlled.
Thanks in advance.
